Catching a segfault in a Python library

Ya got me! Sheesh, I can't hide anywhere :D

I've a bad memory and can't recall what I told PIL at the time. It might
have been a case of waiting to see what new versions can do.

Zigactly! You can wrap try/except around the calls that (by debugging) you
know are the culprits, but a segfault is a segfault and bam! you are at the
command line again.

I'll certainly pop a note. I think, though, that the answer may reside in
the basic theme of this thread:

runapp
 result = runActualApp( )
 while True:
  if result == allokay: break
  else: 
   <Start handling the horror>

Unless a segfault goes through that too, like Krypton through Superman.
